An amusement park debuted a new roller coaster this season, and Peter, the park manager, is interested in the number of people who are riding it. The two data sets below represent the number of riders during the first two weeks of June. Rather than look at all those numbers, Peter wants to select a measure of central tendency that he can use to compare the attendance from week to week. Peter understands that many visitors want to ride the most popular attractions; therefore, he does not want outlier data to have too great an impact. Given that consideration, which measure of central tendency should Peter use to compare the attendance of week 1 to the attendance of week 2?
Peter should compare the median attendance of week 1 to the median attendance of week 2.
Peter should compare the median attendance of week 1 to the mean attendance of week 2.
Peter should compare the mean attendance of week 1 to the median attendance of week 2.
Peter should compare the mean attendance of week 1 to the mean attendance of week 2.
